Explore London while the city sleeps by joining this sponsored walk in aid of Breast Cancer Care. Walkers can choose from a 5, 10 or 20-mile stroll through the capital, winding past St Paul’s Cathedral and Big Ben under the stars. Walkers can write a personal message on a ribbon, which can be added to the ribbon tunnel and will receive a medal at the finish. All money raised will help Breast Cancer Care care for the 62,000 people diagnosed with the most common cancer in the UK every year. Registration is essential here. The minimum fundraising target is £100 per person. Start at Imperial War Museum, SE1 6HZ.
Arrival times: 10 mile 7.15pm, 5 mile 8:15pm and 20 mile 9pm.
